The marine ports in the Philadelphia area are major hubs of economic activity and are vital to the local economy. By volume the Philadelphia ports combine to make the Philadelphia Port System the second largest port in the North Atlantic. These ports provide much needed jobs and revenues. At the same time, port activities result in major emissions from ships, locomotives, and trucks coming in and out of a facility as well as from onsite operations such as the use of cargo handling equipment. As ports grow to accommodate even greater cargo volumes, it is crucial that port stakeholders, including operators, land-owners, community members, and environmentalists, are involved in a collaborative to develop and implement environmentally sustainable business practices. Past examples have shown that implementing such policies is beneficial both for environmental and community health as well as for the long term profitability of the ports.
